PROBLEM TO BE SOLVED: To provide an inertial type electro-acoustic transducer with low harmonic distortion.SOLUTION: The inertial electro-acoustic transducer unit 400 includes a first exciter 100 and a second exciter 200, the second exciter 200 is disposed in a state of being turned over on the first exciter 100, and the cavities of the two cups 40 face each other. The two exciters 100, 200 are fixed together or fixed in one plane intended to cause vibration, the fixation being done in such a way that the axis of the cylindrical support 10 of the coil is coincident. The ends of the coils 1 of the two exciters are connected in antiphase in such a way as to obtain a consistent movement in the same direction as the magnetic unit 4 of the two exciters.SELECTED DRAWING: Figure 5 |
